SMOKE CONSUMER.

Application filed October 14, 1921. Serial No. 507,515.

To all whom it may concern:

Be it known that we, l/VI-LLIAM PETER- SEN and CHARLES D. IVIILLER citizens of the United States, residing at lhicago, in the county of Cook and State of Illinois, have I use of waste energy furnished by the locomotive, so that the power generated by the latter will not in any manner be reduced to insure proper functioning of the invention.

Another object of the invention is the provision of means for supplying fresh air in a preheated state to the fire box of the locomotive, to insure proper combustion at all times, this air and the manner of supplying the same, serving to prevent the formation of a vacuum within the boiler fines and to also maintain the latter in a relatively clean condition.

In addition to the above, the supply of fresh air will permit of a fire being kept within the fire box, with the ash pit doors closed when the engine is working and will maintain the fire at an even temperature for a relatively long period, without attention.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a side elevation showing a portion of a locomotive with the invention applied thereto, parts being broken away and others shown by dotted lines.

Figure 2 is a front view of the same.

Figure 3 is an enlarged side view of the air intake pipe, the latter being partly shown in section and illustrating the means for conducting exhaust steam and air to the air intake pipe. 7

of combustion.

Figure 4 is an enlarged sectional view taken through one of the pipes 1-1 in a plane above the pipes 16 and 1'7.

Pleferring in detail to the drawings,

wherein like characters of reference denote.

corresponding parts, the reference character 10 indicates the boiler of a locomotive, of the usual or any preferred construction, the invention being applicable to locomotives of any make, without changes in structure or in any manner weakening any of the engine parts.

It is the purpose of the invention to arrest the passage of the productsof combustion as they travel from the fire box to the.

Smokestack of the locomotive and return these products of combustion rearwardly into the fire box so that they may be fully and entirely consumed. For this purpose a draft is created irom a point in advance of the boiler fines of the locomotive and this draft travels rearwardly into the fire box, takin up and carrying with it the products To accomplish this there is provided upon each side of the locomotive. boiler between the smoke stack and the forward end, of the boiler casing flues, an airintake pipe 11. These pipes are identical in construction and enter the boiler at the point mentioned and their combined diameters.aresubstantially the same as the diameter of the smoke stack. The intake ends of the pipes 11 are formed of oppositely extending branch pipes 12 and 18, whose combined; diameters are substantially the same as the diameters of each of the pipes 11. Each pipe 12 has its open end forward so that during the forward progress of the locomotive air will be sucked into the pipes 11 through the pipes 12 and the suction thus created will form a suction in the pipes 13 andthus draw in additional air. When the locomotive is moving in a reverse direction, these conditions willbe reversed, that is the pipes 13 will scoop in the air and draw in additional air from the pipes 12. The inner ends of the intake pipes 11 are provided with deflecting hoods 1%, so that the air passing through said pipes will be directed rearwardly through the boiler lines. The admission of air may be controlled through the medium of a damper 15, one of which is positioned in each of the pipes ll.

For the purpose of increasing the draft and preventing the formation of a vacuum within the boiler flues, the exhaust steam of the locomotive (which is otherwise wasted) is conducted into the pipes 11. For this purpose there are provided pipes 16, which convey the exhaust steam from the steam chests upon the sides of the locomotive into the pipes 11. An additional steam pipe 17 leading from the steam space of the boiler, Figure 1, may also communicate with each of the pipes 11. Each of the steam pipes is provided with a distributing nozzle 18,,so as to more evenly distribute the steam throughout the area of the pipes 11 and to more throughly heat the air passing therethrough. The steam not only serves the purpose of providing an increased draft, but causes the air to be thoroughly heated before reaching the flue sheet of the boiler and thus prevents damage thereto.

As an additional means for increasing the draft, each of the air intake pipes 11 has in communication therewith a pipe 19 for the conduct of the air exhaust. This last mentioned means is valve controlled and is only designed for use in an emergency, such as when all of the products of combustion are not being returned to the fire box.

By the use of the present invention, the products of combustion are effectually re turned to the fire box before reaching the smoke stack of the engine and are fed to and consumed by the fire therein. By placing an air intake pipe upon each side of the boiler, a thorough agitation of air occurs in advance of the boiler fiues, so that the products of combustion are thoroughly mixed and carried with the said air to the fire box. This forced draft through the fiues acts to prevent accumulation of foreign matter therein and maintains the fines in a high state of efliciency for a relatively long period,

In addition, the fire within the fire box may be maintained at an even temperature for a relatively long time when the locomotive is not working. This is due to the fact that the ash pit doors may be kept closed, suflicient air for combustion being furnished through the air intake pipes.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

I-Iaving described the invention what is claimed is 1. In a smoke consumer construction, the combination of a locomotive boiler having a fire box and a smoke box and fines connecting said boxes, an air-intake pipe ar ranged alongside and exteriorly of the smoke box and connected at one end with the interior thereof and having at its opposite and intake end branch pipes extending forwardly and rearwardly, respectively, and open at their ends, and means for supplying fluid under pressure to the interior of the air-intake pipe between the intake end thereof and the smoke box.

2. In a smoke consumer construction, the combination of a locomotive boiler having a fire box and a smoke box and flues connecting said boxes, an air-intake pipe ar ranged alongside and exteriorly of the smoke box and connected at one end with the interior thereof and having at its opposite and intake end branch pipes extending forwardly and rearwardly, respectively, and open at their ends, a deflecting hood arranged in the smoke box at the firstnamed end of the air-intake pipe, and means for supplying fluid under pressure to the interior of the air-intake pipe between the intake end thereof and the smoke box.

In testimony whereof We afiix our signatures.
